This invention relates lto a method of and apparatus for preparing fuel for burning. It has for one,object to provide meansaDd a method whereby liuidhydrocarbon fuel which has been who ylor artiallymixed Withair andsubsequently eposited .out of the air may `be .remixed and reatomized to. permit more perfect combustion. This4 rey mixing may be carried out at an kpoint in y thefuel line after the original mixmg. Thus' in the case offa carburetor engine theremixer may be located anywhere and the re-` mixing process may be carried out anywhere between the carburetor and jthe point `of en- 15 trance 'of the fuel into the chamber in which it is tobe burned. -Another object f the invention is to provide `means for separatin out liquid fuel from ,the ,main mixed body an 4for remixing it.v Another object is to dprovide liquid :Euel, holding it separated,` istributin'g 'it about the fuel passa e andremixingand reintroducing it into t e main mixture stream `in an even manner. Other objects will ap' pearfrom time to time in the course vof the specication and claims:

Myinvention is illustrated more or less diagrammatically inthe accompanying drawin s whereinl igure 1 is a cross sectionof an apparatus for carrying out the process; i

Figure 2 isa plan `view'ofthe ap aratus v'in position in a fuel supplyline wit parts in-section;

Figure 3 is a plan v iew of the bottom or downstream side'of the reatomizer core;

Figure 4 is a plan view of the upperor up vstream side ofthe same member.

Like parts are indicated by like characters throughout' the specification` and drawings. A indicates a portion of` the fuel supp y line.l It may be merely a pipe or a portlon of the intake manifold or any suitable inclosed member by meansfofwhich fuell may be conducted to the point of combustion. As here shown -this Vmember is joined yto a second similar membervAl. This latter *member is providedwith an annular depression A2 so.

that the shield of the reatomizer may b'e posiotionedinit'. Y

reato'rnizer proper is formed of ytwo parts, an outer member'or shield B which is generali cylindrical in shape andprovided witllfa` aterally' and outwardly extending "flange B1; 'At its other end it is.' rovided with an inwardly-extending flange 2 which issharpened at' itsinner edge as at B5.

The core or inner member ofthe reatomizer Vis the member C. It is provided at one end with an outwardly extending flange C1. AIt

`is. thickenedftowards oneend asv at Ca and provided with an inwardly extending sharpened fiange or edge C.V The flange C1 extends below the lend of the reatomizer roper vvand thus .providesa'n annular *depresslon C.

When the core'and shield are assembled toc glether as shown in Figlre 1, the depression provides clearance tween the twoV parts exceptfor thelimited vspace where the botl tom of the .flan e Glcontacts the inner face of the member The ange Cserves to vcenter and space the core'` away from the 'shield so'as to provide an annular air space C?.1 `At'approximately the juncture of the flanglaeC1 and the bodyv C-there are formed a r'of relatively small perforations C.

These perforations extend through the thickened part of the memberC and communicate 4with the depression C so thatwhen the partsY are inthe position shown in Figure 1 these perforations extend from the air s ace C to the open s ace formed between the 4ottom of the core and the upper face of the flange B. By reason of thls construction air 'and liquid may pass from the annular space between the sldes of the core and the shield through these perforations and over the partiallv reatomizing edges.

o erative device it will be obvious that many while I have iustmad and' described an i 4c angesimight be made in the size, shape, f

number and distribution of parts 'without departing materially .rom the .spirit-of my invention, andl I wish, therefore, that my 4showingjbe consideredin `a large sense as diagrammatlc.

-The use and operftion of my invent-ion are asfollows.:

y The deviceis inserted somewhere in the fuel lineA ofan internal lcom ustion'engine.

It is so positioned that .the open end of the annular` air space extends toward the upstream side and thus'it faces directly into the current ofgfuel as the latter is drawn into the combustion spaceof the engine. Liquid which has been separated out from thefuel stream or current will be largely deposited on the sidesof theI passage and by reason ofwill act upon this liquidafter it passesv out betweenthe two adjacent sharp edgesCar and B8 and will thus reatomizethe liquid, and by reason of its constructionthis'Yreatomizer will evenly distribute the liquid and so will evenlydistributethe reatomized fuel after it is reintroduced into the main fuel currenty or stream. I, t

' The device therefore prevents the entrance of liquid fuel into the' combustion space by catching itas it runs along the: walls of the fuel passages andit reatoniizes itgfasgabove explained. y v [Iolaim: Y, n
